Heat Transfer - Engineering
Q1: The heat flux (from outside to inside) across an insulating wall with thermal conductivity, K= 0.04 W/m.°K and thickness 0.16m is 10 W/m2. The temperature of the inside wall is - 5°C. The outside wall temperature isA 25°C
B 30°C
C 35°C
D 40°C
ANS:C - 35°C To find the outside wall temperature, we can use the formula for heat flux through a plane wall: totalQ=RtotalΔT⋅A Where:
